Title: Car washing device
Inventor: OOTA YASUHITO
IPC: B60S3/04
Filed: 1985-10-18
Abstract: PURPOSE:To eliminate a waste of water while preventing water from being scattered when a nozzle is directed upward by detecting the inclination of said nozzle, and making control of said nozzle so as to jet out water based on the detected signal. CONSTITUTION:When a nozzle 11 is directed downward, a second shielding body 14b (magnetic body) is moved in between a lead switch 17 and a magnet 18, closing the switch 17, and water is jetted out via a hose 10, through the rotation of a motor. When the jet is to be stopped under this condition, a lever 15 is slightly pulled against a spring 16, a first shielding body 14a-2 (non- magnetic body) is moved in between the switch 17 and the magnet 18, the switch 17 is opened, and the rotation of the motor is stopped, to stop the jet of water. When the nozzle 11 is directed upward, water will not be jetted out since the shielding body 14b is lowered down to the rear end of an inner bore 13a, opening the switch 17. When a car is to be washed under this condition, however, the lever 15 is fully pulled to move the magnetic body part 14a-1 of the shielding body 14a in between the switch 17 and the magnet 18.
